PAPER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 225,990, dated -March 30, 1880.

Application filed September 24, 1878.

To all whom it may concern:

Be it known that I, EUSEBE LEGER, of Waterville, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Paper and Tobacco (Jutting Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a side view, partly in section, through at m. Fig. 2 is an elevation looking at the end containing the handle.

My invention relates to paper and tobacco cutting machines, and is intended to be used as a paper-cutter for printers, book-binders, &c., and also, being reduced to the proper size, as a tobacco;cutter for the cutting of plug-tobacco, herbs, &c.

It consists in the application of well-known mechanical principles in new combination and in compact and durable form to the cutting of paper and tobacco.

In the accompanying drawings, 0 and B are two elbow-levers, hung by trunnions at D and D to the bed ofthe machine I, the leverO being elongated into the arm or handle H. To these levers, at the points a and c, are hung the ends of a knife, A-, and at the points I) and b are hung the ends of the bar E.

It is evident that when the handle H of the lever C is drawn back, as indicated by the dotted lines, the knife, following the points a and a, will be drawn downward and backward to the bed I of the machine with a diagonal motion, which is so essential in the cutting of paper and kindred substances.

Leaving out of account the action of the bar E, it is evident that when the edge of the knife comes near the bed the end which is at B will have a much less downward force than the end at G, for as a moves downward it approaches to a point in the line of D and a, as is shown by their dotted positions, and these three points thus approximate to the condition of dead-centers, resulting in great loss of power in the lever B. At this point, however, the bar or rod E has arrived at a position where b is vertically above D, so that the full effect of the force applied at H is transmitted to a through the bar E, acting on the point 1). Thus throughout the whole stroke the force at the end of each knife A is equalized by the action of the bar E, while without this bar the machine would be inefficient at the latter end of the stroke, as found by experience.

In securing the knife in the manner above described to the levers B and C said levers act as guides to hold the knife steadily in place, thus dispensing with the guides used in some similar machines.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a paper or tobacco cutter, the elbow-levers B and G, hung on trunnions D and D to machine-bed I, and having knife A, hung to them at a a, combined with bar E and bandle H, substantiallyas and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
